,INIPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 97,573. dated December 7, 1869.

.T 0 all whom, it may concern:

Be it known that I, HIRAM J. WArrLns, of Rockford, in the county of Winnebago and State of Illinois, have inventedanew and useful Improvement in Cultivators; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon.

This invention relates to cultivators; and it consists, first, in the peculiar construction of the frame; second, in the arrangement of the devices for lifting the shovel-beams; and, third, in the manner of attaching and holding the shovel-standards to the beam.

- The details of construction and manner of operation will be fully described hereinafter.

In the drawings, Figure 1 is a plan view of my improved cultivator; Fig. 2, a side elevation of the same, Figs. 3, 4, 5, and 6, views of parts detached.

To enable others skilled in the art to make and and use my invention, I will now proceed to describe fully its construction and operation.

This invention is an improvement upon my patent of August 10, 1869. It has for its object to produce a cultivator of simple construction, which shall be well braced and strong enough to resist the strain incident to its work.

The frame consists of the longitudinal beams A A and transverse beams B b b, in addition to which I also employ the braces O O, which terminate in the pole. Thesebraces passbetween the transverse beams b b, and are securely fastened thereto at the point of union. To prevent the frame from being racked and strained apart, I notch the beams b I), by which construction the displacement of the parts is rendered impossible.

E represents a standard consisting of a bent bar the ends of which form its bases, which are secured to the beams A G, as shown. In the upper part of the standard is located the pulley 6, over which passes the chain F.

G represents a curved rack-bar, the upper end of which is attached to the standard E and the lowerend to the beam 0, as shown.

II represents a pivoted lever, provided with the spring-stop devices it h in the usual manher. To it is also attached the upper end of the chain F, the lower end of which is attached to the shovel-beams.

I represents the axle, which is secured be- I neath the beams A O, as shown.

J represents the shovel-beams, and K the shovel-standard. This standard is attached to the beam in a peculiar manner, which will now be described.

L in Fig. 4 represents a hook-bolt which is secured to the end of the shovel-beam by a nut, as shown.

Z represents a bearing-block, which is placed on the inner end of the bolt,between the hook and the beam, and serves to furnish a suitable bearing for the standard.

The construction of my brace M is also peculiar. It is formed, preferably, of flat metal, although round metal will answer as well. Its front end is pivoted to the shovel-beam at a suitable point,in much the usual manner. Its rear end is split and formed into a half-circle, to one end, an, of which is attached the hinge on". The free end of this semicircular hinge is attached to the other end, m, of the brace in any suitable manner by means of a wooden pin. The ring thus formed is kept in place on the standard by means of pins above and below, as shown.

My cultivator, constructed as thus described, is operated in the usual well-known manner, which need not herebe particularly described. Its peculiar advantages will now be set forth in detail. The frame is constructed with the fewestnumber of parts consistentwith strength, and these are so arranged as to form a rigid and unyielding support for the other parts.

The braces O O materially strengthen the frame,

and, in connection with the beams A A, form supports for the standards E. This form of standard possesses great strength and rigidity. Its bases being well spread apart,it cannot be injured by lateral strain. The arrangement of the rack-bar is a desirable-one. By attaching one end of it to the standard, instead of extending it to the beam again, a shorter bar can be used and the material thus economized.

In the employment of a hook-bolt for holding the shovel-standardto the beam all the advantages of the latter are obtained, and, also, the standards can be taken out without removing the bolt from the beam. The arrangement of the brace, also, is such that when the pin gives way, in consequence of a serious obstruction having been met with, the standard can be easily and quickly replaced after the obstacle is passed.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The frame described, consisting of the longitudinal beams A A, transverse beams B b b, and braces O C, the whole being combined and arranged as described, for the purpose set forth.

2. The brace M, constructed as described. with the half-circle m m and hingcm", for the purpose described.

3. The machine described, having the frame A B Z) G, lifting devices E e G H, beams J, and standards K, the wholebeing combined and arranged as described, for the purpose set forth.

This specification signed and witnessed this 24th day of J uly, 1869.
